96.36 Tue Mar 4 07:11:59 CET 2014
10 - semaphores would not clear the destroy hook when interrupted
11 by ->throw, causing segfaults or worse.
12 - ->throw on a thread waiting for a semaphore did not acquire
13 the semaphore, but also didn't wake up other waiters,
14 possibly causing a deadlock.
15 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
16 to report a full stacktrace, which should help find out
17 where the actual call is.
18 - "atomically" destroy data in slf_destroy, because it is
19 the right thing to do, just in case.
20 - disable ecb.h libm dependency, to compile on ancient systems
21 or under adverse conditions.
22
236.33 Mon Nov 18 11:26:27 CET 2013
24 - do not crash when freeing padlists with holes (in 5.18).
25 - tentative SVt_BIND 5.19 port/fix.
26
276.32 Tue Nov 5 15:35:35 CET 2013
28 - use a new algorithm to derive padlists for perl 5.18. The old
29 one could lead to 0-pointer accesses inside perl (reported
30 by Darin McBride).
31
326.31 Thu May 9 07:39:48 CEST 2013
33 - Coro::AIO requests would crash if the thread was ready'd
34 while the request was ongoing.
35
366.29 Wed May 8 02:55:18 CEST 2013
37 - when an on_destroy handler destructs the coro currently being
38 destructed a perl scalar could be accessed after being freed,
39 likely causing a crash.
40
416.28 Wed Mar 6 06:58:02 CET 2013
42 - clean remnants of existing __DIE__ and __WARN__ handlers so
43 they lose their magic and will not cause segfaults later
44 (testcase by Andrey Sagulin).
45 - improved Coro::State documentation a bit.
46 - Coro::Debug::command now flushes the output.
47 - add hack detection code for x32 abi, because the braindead slugs
48 who designed that made it look exactly like x86_64 without
49 providing proper compile time symbols to test for it. as a result,
50 this detection cannot work reliably.
51 - valgrind stack registering was broken.
52 - do not rely on Time::HiRes anymore in Coro::Debug.
53
546.23 Fri Dec 7 23:36:37 CET 2012
55 - use experimental fiber implementation on native windows
56 perls.
57 - use sizeof (void *) as multiplication factor for stack sizes,
58 to accomodate the totally braindamaged microsoft 64 bit "os".
59 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
60 activeperl 5.16 crashes when PerlIO_define_layer is called due
61 to some bug in the perl dll, strawberry perl at least passes
62 the testsuite.
63 - implement Coro::Handle->peeraddr/host/port, for slightly
64 improved compatibility with LWP.
65 - implement 5.17 compatibility by almost blindly applying a
66 good-looking patch by Father Chrysostomos.
67 - move stack management functions into libcoro 3.
68 - libcoro version 3 "released".
69 - support magic values as timed_io_once args.
70 - recommend AnyEvent 7+ or EV 4+, also require EV
71 version 4 or newer for Coro::EV.
72
736.10 Tue Oct 9 01:14:27 CEST 2012
74 - updated ecb.h, it had a typo that caused it to not compile on many
75 big endian systems (reported by many people).
76 - disable memory fences in ecb.h to improve portability.
77
786.09 Sat Oct 6 23:25:02 CEST 2012
79 - Coro::EV I/O watchers were not interruptible by exceptions
80 (Coro::State::throw) (testcase by sten).
81 - ->throw now puts threads into the ready queue, as this seems to
82 be expected by existing code, and code that doesn't cope with spurious
83 wakeups needs fixing anyway.
8 - use fd = -1 in mmap. 84 - use fd -1 in mmap.
9 - cast I32 to int in error message printf. 85 - cast I32 to int in error message printf.
86 - warn about broken so-called "hardened" kernels.
